Principles of vacuum heat treatment process formulation
Vacuum heat treatment equipment began in the 1920s, but its real development began in the 1960s and 1970s, mainly due to the market demand at that time and the research and development of graphite technology. The working environment of vacuum heat treatment is actually Below one standard atmosphe...
Silver sintering technique
Analysis of silicon carbide semiconductor packaging Core technology – Silver sintering technology With the development of electronic industry, electronic products are developing towards the direction of light quality, thin thickness, small volume, low power consumption, complex functions an...
Vacuum hydrogen sintering furnace at 2100℃
This paper introduces the technical performance and structure of the vacuum hydrogen sintering furnace at 2100℃, expounds the working process and mechanism characteristics of the equipment, points out the problems encountered in the installation and debugging process, and points out the solutions...
How to solve the oxidation in gear by vacuum carburizing technology
Vacuum carburizing technology solves the internal oxidation principle Because vacuum carburizing is far below atmospheric pressure of 10kPa (760Torr) under the completion of the pressure, the typical pressure range of low-pressure vacuum carburizing is 400 ~ 666 (3 ~ 5Torr), vacuum conditions mak...
High temperature annealing treatment of silicon carbide crystal
The most common and mature method for SiC crystal growth is still physical gas phase transport (PVT), which is a gas-phase growth method with high growth temperature and high requirements on raw materials and process parameters. In recent years, a great deal of time and energy have been invested ...
Silicon carbide of semiconductor material
Silicon carbide SiC is a compound mainly formed by the covalent bond between silicon (Si) and carbon (C). Its basic unit is si-C tetrahedron, in which Si atom is located in the center and C atom is around. All structures of SiC consist of Si-C tetrahedrons piled up in different ways. Now have fou...
H13 Injection Mold Vacuum Heat Treatment
Overview H13 injection mold steel has high toughness cold and hot fatigue resistance, which can greatly improve the service life of hot mold.At the same time, it can also be used for other shaft types and components that require high strength and hardness, so it is welcomed by the majority of use...
Safe operation procedure for hot cleaning furnace
1. Wipe the greasy dirt or flammable explosive on the surface of hanging tools or workpieces clean. 2. Pull the trolley out of the furnace, then load the hanger or workpiece on it. Note: The loaded workpieces or hangers should not be piled randomly, sufficient consideration should be given to the...
Burn off oven of coating stripping device
1、 Overview The coating stripping Burn off oven is an economic and practical equipment independently developed by our company on the basis of introducing and digesting foreign technologies. Through comparison of treatment effect, cost, environmental protection, labor intensity and other indicato...
Selection of Vacuum quenching Oil for Heat Treatment
The quenching oil is used as the cooling medium in the vacuum quenching process which is called vacuum quenching oil. Vacuum quenching means that metal parts are heated and quenched in a vacuum state [(10～70)×(10-2～10-3) Pa], which means that the entire heating and quenching process is at a ver...
